Power Management

For a laptop, it's very important to properly configure the power management components.

TLP

sudo apt install tlp smartmontools acpi

Enable TLP

sudo systemctl enable tlp
sudo systemctl start tlp

Battery care

Uncomment these lines in /etc/tlp.conf

START_CHARGE_THRESH_BAT0=75
STOP_CHARGE_THRESH_BAT0=80

The service needs a quick restart for it to take effect:

sudo systemctl restart tlp

PulseAudio power management

Pulse sometimes hogs CPU, which can significantly shorten battery life.

Add to /etc/pulse/default.pa

load-module module-udev-detect tsched = 0
